I have a 2016 Scat Pack that was modified on the drivetrain. It has an
Arrington Performance Stroker 426 Gen III hemi with a Whipple 2.9L supercharger with Alky Methanol kit. Coupled to this is
a Paramount Performance Torque Converter onto the Stock Scat Pack A8
transmission. Then a 4" Aluminum one piece drive shaft couples to the 9'
Strange differential. The rest of the drive train has the high speed axles with high angle CVJ boots at the
differential and high speed CVJ to the wheels. The drive shaft, differential, and
axles are from The Drive Shaft Shop [TDSS] in Salisbury, N.C.

BC Racing Adjustable Coilovers are used at the stock Scat Pack suspension
height. I am using M/T 305/45R17 ET Street R drag radials. My best time with a
very favorable DA was 10.24 sec/ 134 mph in the 1/4 mile.

With that background my question to the group is regarding the BC Racing Coilovers and the very tight
fitment of the TDSS high speed CV joints attachment to the rear wheels. There
is such a limited spacing that we have had to use button headed bolts with small
allen slots. Tightening these to the appropriate torque is difficult. We have
tried adding red lock tight but each time after a couple of weekends racing, one of more
bolts get loose. TDSS knows of this issue but says that this is the best
solution considering the tight spacing caused by the lower part of the BC Racing
Coilover cylinder.

Question: Is there another model aftermarket adjustable coilover that has a
smaller diameter lower cylinder to get more space to use regular cylindrical hex
head bolts?

Thanks in advance
